The first thing to clear up is the biggest misconception: a saltwater pool is a chlorine pool. The salt cell splits dissolved salt to generate chlorine on site, continuously, instead of you adding it from a jug. The sanitizer doing the work is the same. What changes is how it gets there.
The advantages are real. Chlorine is produced steadily rather than in spikes, so levels stay flatter between visits. The water feels softer and is easier on eyes and swimsuits. And you stop storing and handling jugs of liquid chlorine, which in a Florida garage is worth something on its own.
The costs are just as real. A salt cell is a consumable with a finite life, typically several years, and replacing one is a few hundred dollars rather than a few dollars. Salt is mildly corrosive over time to some pad hardware, ladders, and light housings, which matters more near the coast where salt air is already doing that job from the outside. And salt systems still need pH watched closely, because generating chlorine this way pushes pH up steadily.
In our heat, both types need the same thing that actually determines success: stabilizer in the right range. Cyanuric acid protects chlorine from being destroyed by the sun, and South Florida sun destroys unprotected chlorine remarkably fast. Too little and you burn through sanitizer by mid-afternoon; too much and the chlorine is locked up and sluggish even though a test says it's there. That balance matters more than which system you chose.
If you're deciding, the practical question isn't salt versus chlorine, it's whether you want to trade a higher upfront cost and periodic cell replacement for steadier day-to-day water and no jug handling. Both make perfectly good pools. Neither runs itself.
